Erik van Nimwegen, from the University of Basel, says there are only small scraps of information and it is “hard to pull anything definitive out of that”. He adds, “one cannot really exclude at all that such a constellation of sites may have occurred by chance”. The authors of the paper concede this is the case. Kristian Andersen, a professor of immunology and microbiology, at the Scripps Research Institute in La Jolla, California, described the pattern, on Twitter, as “random noise”.
Any conclusion that sars-cov-2 was engineered will be hotly contested. China denies the virus came from a Chinese lab, and has asked for investigations into whether it may have originated in America. Dr Washburne and his colleagues say their predictions are testable. If a progenitor genome to sars-cov-2 is found in the wild with restriction sites that are the same, or intermediate, it would raise the chances that this pattern evolved by chance.
Any widely supported conclusion that the virus was genetically engineered would have profound ramifications, both political and scientific. It would put in a new light the behaviour of the Chinese government in the early days of the outbreak, particularly its reluctance to share epidemiological data from those days. It would also raise questions about what was known, when, and by whom about the presumably accidental escape of an engineered virus. For now, this is a first draft of science, and needs to be treated as such. But the scrutineers are already at work.
Controversial new research suggests SARS-CoV-2 bears signs of genetic engineering … china is responsible if this holds uphttps://t.co/Y37S4YCNHN
